METAL EASE-BAR.

Application filed September 15, 1919.

To all; who/1t it may concern:

lie it known that I, Srnnrrono Hnwirr,

Y a a citizen ot the United states, and resident of Atlanta, in the county of Fulton and State 01? Georgia, have invented certain new and useful Improvements in Metal Sash- Bars, oi which the following is a specification, 'ei'erence being had therein to the accompanying drawing.

The object of this invention is to produce iietal sash bars having in manufacture and use advantages over other bars. It involves the use of straight bars which interlock with each other without bending or distortion and form a structure having broad hear ing surfaces and affording unusual resistance to strains tran: we to its plane.

In the accompanying drawings,

Figure l is a perspective view of a portion of one of a set oi parallel bars used in each sash.

Fig. 2 is a similar view of one of two members forming .one of the coacting set of transverse bars.

Fig. 3 shows the other part of the compound bar.

Fig. is a perspective view showing the simple and compound bars assembled and fixed together.

In these views, A represents a preferably rolled metal sash bar having a plane flat hodv web 13, provided at one margin with molded flanges C, (l to support the glass and give pleasing appearance, and having along the opposite margin a narrower bead D. A member oi the compound bar has a plane vveh F equal in width to the web B, but preferably of approximately halt its thickness. his web has at one margin flanges G, G like the flanges (l, C but at the opposite edge has no head corresponding to D. The second member H of the compound bar has a web F in width and thickness like F and is provided along one margin with a head I like the head D. The flanges G. C of the bar A are cut away at J and the l ke flanges or the web E are cut away at K, K to narrow the flanges at this point and form a miter oint with the molded portion of the flanges C, C. The web E is cut away at this point, as shown, at L, to receive the web B. The other web F of the compound bar is cut away at M in like manner, but its bead left intact, while the head I) is cut away to receive it as shown at N. Fig. 1.

It the bar of Fi 1 be dropped over the Specification of Letters IPatent.

bar of Fig. 2 in such manner that its web enters the slot L the flanges will lie in the same plane and those of each member will closely fit in the spaces formed by cutting a vay the companion member. The web of the other part of the compound member is then placed alongside the other thin web in such position that its slot registers with the web 18 and is pressed down until its lower edge rests upon the flanges C, C and its head fits in and fills the recess N formed by cutting a vay the head D. The thin webs when the ash is complete are rigidly held together by spot Welding, screws, or rivets, the latter being shown at O. The broad, plane webs each held accurately in plane form and each having all its recesses filled with unyielding metal give great stillness transversely, and the broad meeting faces at the flange and bead joints help to give stilt ness in other directions.

I have shown but one bar of each set hut: the sash may, of course, have any number of horizontal. bars and of vertical bars and each is secured in the stiles or rails of a sash by means not here important.

The sets of bars are set forth as horizontal and vertical, respectively, but obviously this is not indispensable.

It is especially to he noted that no part 0:! the bars is distorted or in any way in jured in assembling, that no special skill is needed for making perfect sets of assembled hairs after the units are properly made, and that both faces of the sash are plane and smooth. It is also important to note that the structure built up on a plane assembling table is never turned over, the parts being dropped into place, one after another, without even momentarily deflecting any part.

What I claim is:

1. The combination with a sash bar having a plane continuous body web provided at one margin with glass-receiving flanges and at the opposite margin with a bead parallel to the flanges, said flanges and head being cut away to receive Slll'lllfll' parts of a transverse bar, of a transverse her having an analogous web with like flanges and provided with a slot into which the web of the bar first mentioned may be dropped to bring all the flanges into the same plane.

The combination with a sash bar having a plane continuous hody web provided at one margin with glass-receiving flanges and at the opposite margin with a head para lel to the flanges, said flanges and bead being cut away to receive similar parts of a transverse bar, of a compound transverse bar made up of two registering body webs one having flanges at one margin and the other having a bead. at the opposite margin, and both slotted to receive the web of the member first mentioned.

3. The combination with a sash bar having a plane body web slotted to receive the web of a transverse sash bar and provided along one margin with glass-receiving flanges, of a transverse sash -bar having its margins glass-receiving flanges and a read, respectively, both flanges and bead being cut away at one point to receive similar flanges and bead of a transverse bar, and a third bar having its body web slotted like the bar first mentioned and provided at one margin with a bead to drop into the recess formed by cutting away the bead of the second bar.

4. The combination with a sash bar having a plane body web slotted to receive the web of a transverse sash bar and provided along one margin with glass-receiving flanges, of a transverse sash bar having at its margins glass-receiving flanges and a bead, respectively, both flanges and bead being cutaway at one point to receive similar flanges and bead of a transverse bar, and a third bar having its body web slotted like the bar first mentioned and provided at one margin with a bead to drop into the recess formed by cutting away the bead of the second bar, and means for rigidly uniting the webs of the first mentioned and last mentioned bars when assembled. V Y

The combination with a sash bar veb slotted to receive the web of a transverse bar and having at one edge flanges adapted to rest upon a plane table, of an analogous like-flanged, transverse bar with its web adapt-ed to drop freely into the slot of the first bar and with its flanges cut away to pass over the flanges of the first bar and rest upon the table, and means for holding the two bars rigidly in place at all points.

In testimony whereof I hereunto aflix my signature.
